| 20090326547 | COMPRESSED AIR DISSECTOR (AIR JET SCRAPER) - Compressed air dissector is a surgical dissector which is used in tumor dissection and excision phases in surgical branches and especially in neurosurgery and microsurgery. The problem at this point is removal of the tumoral tissue without damaging the adjacent normal tissue and the blood vessels feeding the normal tissue. Moreover, serious difficulties may be encounter in the dissection phase of the arachnoid matter in brain surgery. The occurring adhesions can easily be opened with the aid of the air dissector. This provides great convenience in aneurism surgery. The operation principle of the compressed air dissector is direction of the controlled, sterile compressed air (gas) to the brain parenchyma and removal of the dissected particles from the location with an aspirator system. In said system, the particles in the air are cleaned with a filter system. When the compressed air is directed to the tumor tissue it easily dissects and removes the tumor. In the meanwhile, as no liquids are present in the lacuna the operation site can be seen clearly. Furthermore, event the smallest vessels are protected. Thus, peroperative bleeding occurs less and the postoperative wound curing becomes more physiologic. Moreover, tissue damage due to thermal effect is out of the question during the use of compressed air dissector. | 12-31-2009 |
